Final answer:
The advantage of learning approaches in studying personality is their focus on observable and measurable behaviors, allowing for scientific testing and empirical evidence.
Step-by-step explanation:
The advantage of applying learning approaches to the study of personality is that it focuses on observable and measurable behaviors. Unlike the psychodynamic approaches, which relate personality to inner processes, learning approaches can be scientifically tested because they deal with observable phenomena. By using learning approaches, researchers can gather empirical evidence to support their theories and make objective conclusions about personality.
